Summary of the invention
The object of the present invention is to provide a kind of multi-functional reaction frame for self-balanced loading, to solve the problem that reaction frame in the prior art is restricted to the experiment place and can't realize self-equilibrating.
In order to reach above-mentioned purpose, solution of the present invention is:
A kind of multi-functional reaction frame for self-balanced loading wherein, comprising:
The bottom girder has two that are arranged side by side;
Loading frame has the loading column and the two ends that are separately fixed on the girder relevant position, bottom and loads the loading crossbeam that column is fixedly linked with one respectively;
Support frame has the support beam that the bearing column that is separately fixed on the girder relevant position, bottom and two ends are fixedly linked with a bearing column respectively.
Further, this loads between crossbeam and loading column and/or this support beam and the bearing column and is connected by bolt.
Further, this loads between column and bottom girder and/or this bearing column and the bottom girder and is connected by bolt.
Further, this bottom girder, loading frame and support frame all adopt H shaped steel.
Further, the top flange of this bottom girder is arranged at intervals with a plurality of confessions and loads the bolt hole that column or bearing column are fixedly linked.
Further, also be provided with transverse screw between this two adjacent bottoms girder.
Further, be arranged at intervals with a plurality of fixing bolts hole of transverse screw that supply on the web of this bottom girder.
Further, be arranged at intervals with a plurality of fixing bolts hole of crossbeam that supply to load on the web of this loading column.
Further, this reaction frame also comprises the ribbed stiffener that is arranged on bottom girder, loading frame or support frame.
After adopting said structure, the reaction frame that the present invention relates to, it can carry out static test to steel truss and reinforced beam, and its bottom girder directly is seated on the ground and can uses reaction frame, thus the present invention has the effect that does not limit the place to use; Simultaneously, the present invention can form the counter-force system of a self-equilibrating by being fixedly linked between its bottom girder, loading column, loading crossbeam, bearing column and the support beam, thereby makes the present invention can realize that self-equilibrating loads; In addition, the present invention has also further that simple in structure, power transmission route is clear and definite, loading and unloading property is strong, good stability, can adapt to the high characteristics of size flexibility ratio.

Embodiment
In order further to explain technical scheme of the present invention, the present invention will be described in detail below by specific embodiment.
As shown in Figures 1 to 4, it is a kind of multi-functional reaction frame for self-balanced loading 100 that the present invention relates to, and it comprises bottom girder 1, loading frame 2 and support frame 3, wherein:
This bottom girder 1 has two that are arranged side by side;
This loading frame 2 has the column of loading 21 and loads crossbeam 22, and this loading column 21 is fixedly linked with bottom girder 1, and is separately positioned on the relevant position of each bottom girder 1; 22 on this loading crossbeam is erected at two and loads between the column 21 relatively, and two ends are fixedly linked with a loading column 21 respectively;
This support frame 3 has bearing column 31 and support beam 32, and this bearing column 31 is fixedly linked with bottom girder 1, and is separately positioned on the relevant position of each bottom girder 1; 32 of this support beams are erected between two relative bearing columns 31, and two ends are fixedly linked with a bearing column 31 respectively; This bearing column 31 and support beam 32 can be set to many groups according to concrete needs, are two groups in the present embodiment, and be positioned at this loading frame 2 near;
Can be convenient to dismounting in order to make the reaction frame 100 that the present invention relates to, as shown in Figure 1, this loads between crossbeam 22 and the loading column 21, all is connected by bolt 4 between this support beam 32 and the bearing column 31, between this loading column 21 and the bottom girder 1 and between this bearing column 31 and the bottom girder 1.Like this, the reaction frame 100 loading and unloading property that the present invention relates to are strong, thereby have the advantages that to be convenient to carry.
In order to allow the reaction frame 100 that the present invention relates to can generally be applicable to concrete steel truss and reinforced beam, the top flange of this bottom girder 1 is arranged at intervals with a plurality of confessions and loads the bolt hole 11 that column 21 or bearing column 31 are fixedly linked.Like this, the loading frame 2 and the support frame 3 of diverse location just can be set on this bottom girder 1 according to the characteristics of concrete test specimen, perhaps adjust the spacing between loading frame 2 and the support frame 3.In order further to mate test specimen, be arranged at intervals with a plurality of bolts hole 211 on the web of this loading column 21 for 22 settings of loading crossbeam, like this, just can realize different loading height.
